They do Lol ..at least to the one I went to they did
It was like a choo choo train of carmelldansen dancers XD it was sooo long!
The koolest part was they were all mostly in cosplay <3

Ohhh and me and my best buddy always do carmelldansen during lunch =P
Our other friends say 'oh my gosh, they ain't it again =.='
And me n' my bud wanna put all of our friends doing the dance and put it on youtube too ^^!

Ugh... from where I live, they always play that song along with annoying high pitched vocaloid songs. It's like Akihabara here. There's just so many weeaboos it's not even funny. It's a miracle that my ears are still intact.
